Emergence of Replication Timing
The Emergence of Replication Timing is a specialized area within biology that focuses on understanding how the timing of DNA replication is established and regulated during early mammalian development. This field investigates the ordered sequence in which different regions of the genome replicate, known as the replication timing (RT) program, which is crucial for maintaining genetic stability and proper cell function. The design purpose revolves around exploring the development regulation of RT in mammals, particularly from the zygote to the blastocyst stage. It involves techniques like single-cell Repli-seq to generate genome-wide RT maps, offering insights into how RT contributes to genome organization, the epigenome, and the interplay with transcription. An example scenario illustrating its importance is the gradual definition of RT from the 4-cell stage in mouse embryos, highlighting how early embryonic development is closely linked to the establishment of the epigenome and nuclear organization.
